Default Need Help Chipping My ECU for ZC!

I have a 1990 Civic Hatch with the ZC engine and tranny. The current ECU in there is the PR4, I was told someone in this forum could help me chip it properly with the right fuel settings for the DOHC ZC. The car had been hesitating pretty bad lately but i just changed the fuel filter and it shifts smoother and drives alot better. When the car is cold or just started the engine seems to miss and bog alot. What is the problem? Any info would be helpful! Thanks to All.

Well, for one, you're running an ECU tuned for a 1.8 DOHC, not a 1.6 DOHC.. So I imagine you're having a rather large issue with being rich. Oh well..

you're better off picking using a PM6(CRX SI) or PM7(JDM DOHC ZC) ECU.

A PG7 (89 Integra) Ecu is also fine but if you wanna go towards chipping.. i would say go with a PM6 ECU.

Well, the PR4 is chipable, just run a PM7 (ZC ECU) maps on it. Very simple.

Open the PR4 ROM in TurboEDIT, import the ZC tune from the TurboEDIT Map Library, save, and burn. Your fuel/ignition table problems are then solved.
